I-IR-CUT Dual Filter Switch ye-CCTV ip Security Camera Lens Projector
Ngaphakathi kwikhamera, i-CCD okanye i-CMOS isebenzisa isihluzo sasemini nasebusuku kuba umfanekiso wekhamera unebala elingaphelelanga emini, umbono wasebusuku unesiphumo esiphantsi sokukhanya, ngoko ke isihluzo sasemini nasebusuku asinakukwazi ukuhlangabezana nesicelo sangoku soshishino lokujonga i-CCTV semveliso yedijithali ephezulu, xa ikhamera inombala, iya kusebenzisa ngokuzenzekelayo isignali ye-pulse ukwenza iswitshi itshintshele kwisihluzo se-IR CUT, isuse umfanekiso wekhamera kufutshane nombala oyintloko, indalo. Xa ikhamera ibona ebusuku, isebenzisa isignali ye-pulse ukwenza iswitshi itshintshele kwisihluzo se-AR kwakhona, esi sinzwa somfanekiso sinokubangelwa kubude bonke bokukhanya, ukuze ikhamera ibe nokukhanya okungcono kunye nesisombululo somfanekiso, kwenziwe izinto zibe lula ukuzibona.
Iswitshi ye-IR-CUT sisixhobo esibekwa phakathi kwesensa yekhamera kunye nelensi, kwaye ivumela isihluzo se-IR-Cut ukuba sibekwe okanye sisuswe ngaphambili kwesensa, kuxhomekeke kwinqanaba lokukhanyisa. Sisivalo somatshini, esidla ngokusebenza ngemoto, esinesihluzo se-NIR kunye neepaneli zeglasi ezingenanto.
